EXPERIMENTAL

• Bugfix with Spin controls. Clicking on spin buttons would not visually update spin value
• Bugfix with miner sms/email merge. 'Send one' button was always greyed out
• Bugfix with convert account. Could not convert zero balance account customer to cash customer
• Tweaks to keyboard focus changing logic.
  • Example: Adding parts in Point of sale. After adding part sometimes focus would goto list of parts, not to 'part number 'entry box where it should.  Prior version fixed this too (hack fix), but this change fixes root cause problem in GUI
  • Error and crash was triggered sometimes. Crash relates to this part of software behaviour.
